Benefits of using this Facebook Undo Extension:

✔ A post that you undo using this extension is never published (so Facebook will not be logging your status. Facebook is known to save your data even if you delete it).

✔ Without the extension, simply deleting a status on Facebook does not work fast enough for people not see the original post - the status might still be shown on your friends' feed for a couple of minutes (because of Facebook caching mechanisms).

Facebook Undo Chrome Extension let's you undo your facebook status post by giving you a 5 seconds grace period during which you can regret and cancel the post.
